In 2018, colorectal cancer was the third-most common diagnosed cancer among both men and women in the U.S., and data indicate that younger adults are increasingly being diagnosed with it. A new research initiative will examine how the microbiome—a collection of trillions of microorganisms throughout the body—affects the development of colorectal cancer. Scientists on the team will also seek out ways to manipulate the microbiome to better prevent and treat colorectal cancer.

In this week's episode, part two of our miniseries on cancer prevention, we're speaking with one of the co-principal investigators of the team, Wendy Garrett, professor of immunology and infectious diseases at Harvard T.H. Chan School of Public Health. Garrett is also on the steering committee of the Zhu Family Center for Global Cancer Prevention. In part one of our miniseries, we spoke to Timothy Rebbeck, the center's director.

Working from home has its perks: Better coffee, easy commute, no fluorescent lighting. But, as any home office worker can tell you, there are also downsides: No more office social hours, no more ergonomic chairs, and no more quiet train rides to catch up on your podcasts.

As COVID-19 swept through American prisons and jails in 2020, wardens scrambled to keep prisoners and corrections officers from getting sick. One strategy was to increase solitary confinement. Health experts warn that solitary confinement increases the risk of mental illness and suicide, but the practice continues. Today, about 2 million people are incarcerated in the U.S. In this episode of the Better Off podcast, we'll ask: Is it possible to build a corrections system that accounts for their health and safety?

How can we protect the health of incarcerated people?

It’s estimated that half a million Americans are experiencing homelessness. Even a brief period of housing insecurity can make existing health issues worse, and bring up new physical and mental traumas. Doctors and nurses who help patients navigate these issues have a prescription: More housing, and more services. Is it possible to end chronic homelessness, even as eviction moratoriums end and rents increase? And is a housing-first model the best way to achieve that goal?

Can we end chronic homelessness?

What does a plate of healthy food look like? Everyone has an opinion – from doctors to dieticians to wellness experts. But advice on what to eat often ignores a big factor in how and why we make meals: Culture.

In this episode, we’ll ask: Are we better off when diet and nutrition advice is informed by culture?

What makes a meal healthy?

It seems like every brand of makeup, fragrance, and hair care wants consumers to believe that their products are safe, natural, and clean. Is this all just greenwashing? The beauty industry is remarkably unregulated – and women, particularly Black women, bear the highest health risks from chemicals in everyday products. In this episode, we’ll ask: How can we decide what beauty and skincare products are safe to use?
